Interior and Exterior Signs Letter Size Matters

Signs are used to connect with and attract new clients and customers. When you are designing your window sign (window graphics), banner, or car graphics or vehicle wrap you always want to make sure your target market can read what you want them to know about your business. The size of your letters and logos, and the colors you choose are crucial in creating interior and exterior signs that are visible and easy to read sign.

There are Letter Visibility Charts showing the maximum reading distance for maximum impact, and the overall readable distance. A good rule of thumb is every 1 inch of letter height equals 10 feet of readability for maximum impact. 3in. tall letters have their best impact within 30 ft.; however, it can still be seen and read at up to 100 ft.

When designing any commercial sign, consider the most important message, and how far away are the readers you are wanting to impact. If you are placing an interior sign for a sales ad in a retail store, your text need only be visible to the people in the store, so 1-2” or less would work just fine. However, if you are hanging a banner and want drivers on a nearby highway to be able to see your exterior sign, you would design your letters at 3”minimum, preferably much larger.

Font types also impact visibility of your text on interior signs as well as exterior signs. Very thin fonts and script fonts can potentially decrease visibility. A bold style font that is easy to read with sufficient spacing between letters is best for visibility on any sign. You can test this by typing in a few words in a computer program at different font styles, colors, and sizes, and printing them out and posting them on a wall. Stand back and view them at different distances to see how all these aspects come into play in choosing the proper lettering for your sign.

When you want the best impact on those you are trying reach you will need to consider a number of things. The size, colors, and styles you choose should all depend on what you want as your end result. Always consider how your sign will be viewed and who you are trying to reach. Trying to save a few dollars by purchasing smaller letters is not a wise decision; you may be wasting your investment and efforts when the sign cannot be read by the customers you are trying to attract. Be size wise!
